There are two "Rohtas" in the Indian subcontinent - one in Punjab (now in Pakistan) and the other in Bihar (Rohtas district presently). The coins with Rohtas mint name are attributed to the Rohtasgarh or Rohtas Fort in Bihar on the stylistic grounds as these are very similar to the issues of Patna mint coins in style. The Fort of Rohtas which was once ruled by the Raja Man Singh, then the General of Emperor Akbar around 1558 AD came under the stronghold of Prince Khurram (Shah Jahan) in rebellion against his father who by this time was sinking steadily into the clutches of Nurjahan and his vice of opium. The rebellion ended with a reconciliation in the year AH1035, RY 21 when Khurram agreed to hand over Rohtas Fort back to his father. In 1624/RY19, Murad Baksh was born to Khurram and his wife Mumtaz Mahal in Rohtas. The celebrations of his birth continued for a long time and were a costly affair. It is plausible that the coins might have been struck and issued around this occasion.

Half rupee is possibly unpublished and unlisted in all the major references, only one known example was offered in an international auction 10 years ago.

One of the highest rarity of Jahangir Half Rupees.
